High altitude display available. Control Via keyboard, Windows™ OS Scene Image, automated sensor health diagnostics, signal level display Ethernet-ready remote diagnostic capability Swappable mass storage Up to 5 ITRES imagers may be simultaneously operated via MuSICTM System GEOCORRECTION/ORTHOCORRECTION SOFTWARE • Best nadir pixel selection function during mosaicking • Accepts Lidar, Ifsar, and USGS DEM inputs • Nearest neighbor algorithm used – maintains radiometric fidelity • Separately stores ancillary data (e.g. pointing vector, DEM) MOSAIC HOURLY COVERAGE Real-world operational assumptions: 35% sidelap, 3.5 minute turns, zig-zag flight direction, integration time flexibility used to optimize for faster aircraft ground speed within typical fixed-wing survey speed range. Note that as the CASI is both spectrally and spatially programmable, many other band number/airspeed/ pixel resolution combinations are possible. Four simple examples (smaller pixel resolutions possible): • Up to 212 km2 at 1.25 m spatial resolution and 144 bands (110 knots) • Up to 230 km2 at 1.0 m spatial resolution and 72 bands (150 knots) • Up to 248 km2 at 1.0 m spatial resolution and 36 bands (162 knots) • Up to 93 km2 at 0.5 m spatial resolution and 48 bands (121 knots) SPATIAL RESOLUTION & FLIGHT ALTITUDE DATA PROCESSING SYSTEM CASI-1500 imagery, Antarctica, 2011.
